My invention relates to a1 hose retraction assembly for lling stationgasoline pumps. The desirability of housing the hose` of a gasoline pump within the pump hasbeen long recognized. It improves the appearance of the pump and station, safeguards the. hose',v and permits the use of a longer hose than that` possible with the external suspension now coirlmor'ilyused. However, when this self contained storage. is desired, a retraction mechanism is' anl essential element of the pump. To b e, most satisfactory, the retraction device should permit a. free withdrawal of the hose and have no rsletracting force acting while the hose is in use andyetprovide apositive and certain retractionlwhen desired.V

One object of my invention,` therefore, is to provide a novel assembly for a motor fuel pump which, while permitting free withdrawal and easy retention of the hose'. will. retractthe hose when the operator so desires. Y

Another object is to provide a novel hose retraction assembly which is motor actuated to aiordy positive, strong, and `sure response.

Yet another object is to providea novel hose retraction assembly which isv powered by the pumping motor of the pump.

Other objectsand advantages of my invention will be apparent from/the following description and drawings, of which:

My invention is intended to be incorporated in a gasoline pump l which may otherwise be conventional and which has a pump unit I2,powered by a motor l. The pump withdraws gasoline from a reservoir (not shown) and circulates it via a line I6 through ameter lrwhich operates a recorder 2t and to a point at which myinventionAmay-be introduced into the structure.

Myinvention comprises a stationary housing 3U which is securedto the-oor-32 ofthe pump I0 by. bolts i-or. by/a-nyother suitable means.A Up- Wardly 4of the Vfloor the housing-is-formedto pro- 2` Claims'. (Cl. 242-86) vide a shallow, substantially cylindrical recess 38 which serves the purpose of defining a retraction gear case. A smaller recess @IJ is formed approximately centrally in the case 38 and is threaded internally as at 42 to' provide a reel spindle seat. An opening Mis' formed in the side adjacent the bottom of' this recessk which communicates with the passage 4G formed integrally with the housing. The other end ofthe passage is internally threaded to receive an elbow 43 which in turn connects the retraction assembly with the fuel line It and pump l2l Upward ci the reel spindle seat 4o a cylindrical gear spindle opening 54 is formedY in the retraction gear case. The edge 56 of the retraction gear case is machined to furnish a bearing surface for the hose reel. A tubular reel spindle Evil is threaded into the reel spindle seat and a hose reel body is rotatably mounted thereon.

The hose reel body comprises the inner wall 62 of the reel which has on its reverse side a bearing surface te adapted to cooperate with the surface 56 to provide additional support for r the reel other than the spindle 5B. A central opening 66 is formed in the wall defined by a iiange 68 which serves as a bearing for the rotation thereof about the spindle. Ball thrust bearings 'lll are interposed on the spindle between the bearing iiange ti? and the spindle seat. On the side of the wall opposite to that from which the bearing Iiange E6 projects, a packing gland 'l2 is formed coaxial with the opening t6 and having a larger diameter than the bearing ange. When the hose reel body is properly positioned, the packing gland coaxialiy surrounds the free end of the spindie leaving an annular recess between these meinbers. Annular packing rings it are seated in the recess and embrace pliable rings of packing inaterial is. The rings are loaded by a spring it, the opposite end ofwhich bears against an annular member SS overlying the end of the reel spindle 58 and secured thereto by screws The hose hub is formed as a flange 8d which pro jects outward from the wall 62 on the same side as the packing gland 'i2-and preferably comprises one turn oi a spiral with a radial wall 8S joining its ends. This wall has a tappedV hole 83 through it to which the hose may be secured. The hub flange continues from its outstanding portion ed radially inward parallel to the wall 52 as at s2 to approach closely the end of the packing gland l2. Sufficient space remains, however, to leave a passage dil. From this point the ange again extends outward and is threaded at St to receive cular cover plate is secured to the hub flange portions 92, and serves as the other wall of the reel.

The hose reel body has a shoulder |02 formed thereon at the juncture of the wall 62 and the bearing flange 68 coaxial with the latter. On this is mounted a driven gear |04 secured to the body by screws |06 or other suitable means. This gear is meshed with the intermediate pinion |08. The pinion |08 is mounted on a gear spindle ||0 by a pin H2. The spindle carries an intermediete gear I Iii on its other end and a bushing I I6 intermediate the pinion and the gear. The bushing i IS is rotatably fitted into the spindle opening till of the housing. Thus, the spindle l I0 is rotatable relative to the housing. The bushing ||6 nts into the housing so as to have an integral portion I i8 thereof projecting outwardly thereof.

To this is fitted a gear case I, the two being secured together by a set screw |22. The gear case is, therefore, rotatable with the bushing relative to the housing St. The intermediate gear IM is situated in the housing. A driving pinion il, formed integrally and coaxially with a pulley spindle i251 is also enclosed in the gear case in mesh with the intermediate gear H173.

The spindle |25 is formed to have a stub end |23 jcurnaled in a bearing equipped recess |30 in the inner wall of the gear case and a longer pro'ection on the other side of pinion I|4 which passes through a gear case cover |32 and has a pulley |34 mounted thereon. rIhe cover is secured to the gear case |20 by bolts |35. The opening in the gear case cover has a bearing sleeve It therein to receive the pulley spindle. The shape of the gear case may be best seen in `Fig. 3. The spindles IIB and |25 are parallel and in substantially the same horizontal plane. The gear case houses the gear i ifi and the pinion lit which are constantly meshed. It is pivotally affixed to the housing by the spindle lIi. The part of the case, therefore, which houses the pinion |2=i may move arcuately up and down carrying the pinion, the spindle IS, and the pulley |313 with it about the center I Iii.

A shift rod |38 is pivotally secured to the gear .case at one end as by a bolt |4| or other' suitable means at a point under the spindle |25. At the other end a fork |42 is secured to the rod which ,in turn is linked to a pedal lever |46 by a pin or bolt MG. The fork engages the lever between a pivot Ifl secured to the housing and the free end thereof. A tension spring |52 is connected between a pin Ieri on the housing and a pin |55 on the pedal lever to maintain the shift rod in its upper position when no force is being applied to it.

The retraction assembly is powered by the pump motor |13, a double belt pulley |50 being provided on the shaft of the motor. This pulley comprises an externally threaded shaft |82 adapted to be fitted over the motor shaft and having an integral flange |641 formed thereon adjacent to the motor. The ange surface |66 away from the motor is inclined to provide one side of a V belt groove. An adjustment member its having a threaded central opening adapted to be received on shaft |62 is secured thereto. This member has a flange |10 formed on the inner end thereof whose inner surface |12 is inclined to complete the V belt groove. Outwardly of the frange a flat belt groove |15 is provided. rThe pump is furnished with a V belt |16 which drives the pumping mechanism, and a flat belt l 18 which drives the retraction mechanism.

In operation the hose retracting assembly embodying my invention functions in the following manner. In the rest position when no force is exerted on the lever |44 the spring will hold it in its uppermost position. The lever in turn holds the shift rod |38 in its upper position which rotates the gear case about spindle III) to move the pulley |34 from tight or driving engagement with the belt |18 so that the belt may rest loosely upon the pulley. As the motor is started the V belt remains in tight engagement with the motor and pump whereas the fiat belt is loose and will transmit no power to the hose reel. The hose may hence bewithdrawn and held while lling an automobile gasoline tank without any retracting force being exerted by the assembly.

To retract the hose, the operator steps on the pedal lever |44, it being understood that the means of actuation may well be a manual lever or any other appropriate means. This has the effect of rotating the gear case |20 downwardly about the spindle |I0 which places the pulley in tight driving engagement with the belt |18.

Power is transmitted from the motor which remains in continuous operation by the pulley through the driving pinion |24, the intermediate gear ||4 and pinion |08 and the driven gear |04 to the reel body 60, retracting the hose.

The course of flow of the gasoline through this device is as follows: The passage 46 is connected by the elbow 48 to the gasoline line I6. The fuel enters the elbow and iiows through the passage to the end thereof which overlies the reel spindle seat. It then moves through the seal'l and tubular spindle 56 and out into the passage 94 and the hub 84. The packing 16 eifectually prevents leakage of the fuel out of the apparatus. From the hub it flows out of opening 88 and into the hose.

The double belt pulley |60 serves an important function in the assembly. In adjusting the unit lfor operation the motor must be positioned and retraction assembly may result in an incorrect spacing between the motor and the pump for a standard V belt. This may be corrected by turning the adjustment member |68 on the shaft |62 to make surface |12 approach or recede from surface |66. In this fashion the effective diameter of the V belt groove is changed to shorten or lengthen the effective length of the belt.

While I have shown and described a preferred embodiment of my invention, it will be apparent that numerous variations and modifications thereof may be made without departing from the underlying principles of the invention. I, therefore, desire, by the following claims, to include within the scope of the invention all such variations and modifications by which substantially the results of my invention may be obtained through the use of substantially the same or equivalent means.
